SEATTLE (AP) — Officials have identified the female snowshoer who was killed in an avalanche Saturday in the Cascade Mountains east of Seattle.

The King County medical examiner’s office said Monday that 55-year-old Joy Yu died of mechanical asphyxia due to being trapped under a snow avalanche.

Yu was hiking with her dog at Red Mountain Saturday afternoon when she was caught in an avalanche. A group of snowshoers managed to dig her out of 5 feet of snow, but she was pronounced dead hours later after being transported by rescuers down the mountain.

Rescuers on Monday suspended a search for a 61-year-old hiker who was caught in a separate avalanche Saturday in the Snoqualmie Pass area.
